CUPERTINO, Calif., May 10, 2013

CUPERTINO, Calif., May 10, 2013 /PRNewswire/ -- DURECT Corporation (Nasdaq:
DRRX) today announced that Pfizer has provided an update on Remoxy as part of
their Form 10-Q filing. Pfizer's disclosure is as follows: "In 2005, King
Pharmaceuticals, Inc. (King) entered into an agreement with Pain Therapeutics,
Inc. (PT) to develop and commercialize Remoxy. In August 2008, the FDA
accepted the NDA for Remoxy that had been submitted by King and PT. In
December 2008, the FDA issued a "complete response" letter. In March 2009,
King exercised its right under the agreement with PT to assume sole control
and responsibility for the development of Remoxy. In December 2010, King
resubmitted the NDA for Remoxy with the FDA. In June 2011, we and PT
announced that a "complete response" letter was received from the FDA with
regard to the resubmission of the NDA. We have been working to address the
issues raised in the letter, which primarily relate to manufacturing. We met
with the FDA in March 2013 to discuss our plan to address the June 2011
"complete response" letter. We received written guidance from the FDA in May
regarding required next steps, including additional clinical studies, to
address the letter. Based on this guidance, we are considering our options
with respect to Remoxy. If we elect to continue development of Remoxy,  we 
would not expect to submit a response to the "complete response" letter before
